Step 2: Remove and Clean the Basket
- Take out the basket and any accessories.
- Use warm, soapy water and a non-abrasive sponge to clean away any grease or food residue.
- Dry thoroughly before reassembling.
Step 3: Check for Residue or Grease Buildup
Inspect the heating element and interior of the basket for grease or food particles. Use a soft brush or cloth to gently remove stubborn residues. Avoid abrasive cleaners that may damage the surface.
Step 4: Examine the Door Seal and Vent Area
Ensure the door seal isn’t damaged or dirty, which could cause smoke leaks. Clean the seal and vent area with a damp cloth, and make sure nothing obstructs airflow.
Step 5: Use Proper Liners and Avoid Overfilling
Using liners like those from Cosori or compatible accessories can prevent grease from accumulating. Do not place liners during preheating or overfill the basket, as excess food can cause smoking or fire hazards.
